Abstract

Un sistema de sujeción libre de pernos para ferrocarriles de transporte pesado, que comprende la traviesa de hormigón (1). Una superficie superior de la traviesa de hormigón (1) está provista con dos espaldones de hormigón (2); se forma un rebaje de soporte de riel (12) entre los dos espaldones de hormigón (2); las primeras bases de hierro (3) se entierran previamente en los lados internos de los espaldones de hormigón (2); una superficie de la parte superior de cada primera base de hierro (3) se apoya en una superficie del espaldón de hormigón (2) que mira hacia el lado interior; una parte principal de la superficie de apoyo de la parte superior de cada primera base de hierro (3) contra el espaldón de hormigón (2) es una superficie inclinada (9); los espaldones de hormigón (2) forman respectivamente pendientes coincidentes (13) en posiciones donde los espaldones de hormigón (2) se apoyan en las superficies inclinadas (9) de las primeras bases de hierro (3); las pendientes (13) y las superficies inclinadas (9) están fundidas juntas; sobre las primeras bases de hierro (3) se instalan tiras elásticas en forma de arco (6); se proporcionan bloques patrón (7) en los lados internos de las primeras bases de hierro; los bloques patrón (7) se fijan por medio de las tiras elásticas en forma de arco (6); y los bloques patrón (7) se pueden fijar en un cuerpo de riel de un riel de acero (8) ubicado en el rebaje de soporte del riel (12), o se pueden sujetar en una almohadilla de hierro (15) en la parte inferior del riel de acero (8). El sistema de sujeción libre de pernos es particularmente adecuado para su uso en ferrocarriles de transporte pesado con una gran carga por eje de 40 toneladas o más.
